I am currently making an analysis of a codec system that can encode up to 2 wave files into 1 file and decode it. Here is a simple illustration:
L+R ---> ENC --->L'+R'
with L'=L+∂1 & R'=R+∂2
The codec is not lossless and we are analyzing if there is any leakage from one source to another, some kind of crosstalk, if you will.
So what I have to do is find out if
∂1 has traces of R &
∂2 has traces of L.
I feel a general approach would be to subtract L/Ldec to get
∂ and then compare that
∂ to R.
I have done some reading on correlation but it's all a little vague at the moment.
So, onto my question(s):
- Is this possible with limited knowledge of DSP (reading up but it's a lot & not that easy)?
- If not, on what should I do some reading (From what I've gathered so far: correlation & Pearson's coefficient)?
- Is there some sort of standardized test for this - I presume there is but I can't find any!
Even though code snippets would be handy since I only just started to use MATLAB & still am somewhat inexperienced, the main point of this topic is understanding so I can implement it. If someone else implements it I won't learn!
